A systematic demographic efficiency analysis of U.S. interstate population exchange, 1935-1980.

"Evolving patterns of population redistribution within the United States are examined for the period 1935 to 1980. The demographic efficiency measure is employed to assess the compensating or non-compensating nature of migration to and from each state. This measure is then extended in order to examine the entire system of state-to-state movement streams. Using the analytical technique of Q-analysis, systemic change is shown to have taken place. It is argued that the geographic pattern change reflects a nexus of economic and societal trends associated with post-industrialism."
